What does "unstaged changes after reset" mean in git?

@darrion.kuhn 

"Unstaged changes after reset" means that there are changes made to files in the working directory that have not been added to the staging area. This can happen after using the "git reset" command to undo changes to the last commit. Git is warning you that there are changes that were not reverted by the reset command and are still present in the working directory. You can review and stage these changes before committing them or use additional git commands to discard or revert them.
